  1. C   plants are more efficient in their use of CO2
  2. C   plants are able to obtain the same amount of CO2 by keeping their stomata open for shorter periods of time.
  3. C4 plants don’t use CO2 as their source of carbon.
  4. C3 plants are more limited than C4 plants by CO2 availability because of transpirational water loss.

During exponential phase in batch culture, the growth rate of a culture is proportional to the concentration of cells present. When Streptococcus lactis bacteria are cultured in milk, the concentration of cells doubles in45 min. If this rate of growth is maintained for 12 h, what is the final concentration of cells relative to the inoculum level?
